Weather stripping



April 6, 1937. D. A. SELIGMAN WEATHER STRIPPING Filed May 15, 1935 R 5 M A M Patented Apr. 6, 1937 UNITED srrs PATENT OFjFiCE 7 Claims.

The present application relates to weather stripping to be utilized in and around the Windows, doors and other opening closures in household or other buildings.

Among the objects of the present invention is to provide an improved inexpensive, easily applied weather stripping which may be made of stamped sheet metal and which will assure adequate protection against the ingress of weather 10 Without at the same time interfering with the operation of the window, door, or other opening closure to which it may be applied.

Another object is to provide an inexpensive, readily applied sheet metal window stripping which may be particularly applied to windows, which will assure adequate protection with varying climatic conditions from winter to summer and of different humidities, and which will not interfere with the raising or lowering of windows even after usage for a longer period of times.

Other objects are in part obvious and in part pointed out hereinafter.

In accomplishing these objects according to the embodiment of the invention, it has been found most suitable to provide angle strips, the angles of which are usually substantially less than 90, but in any case desirably more acute than the angle of the frame to which they are applied. The ends of these angle strips may be provided with extension members .or fingers to be turned over the corner .of the end of the panel or frame to which they are applied to enable adjustable or fixed connection thereto.

In one form of the present invention the ends of the angle member are split so as to form two fingers at each end, which may be slotted or provided with openings to enable them with automatic adjustment to be screwed or attached to the end of the frame to which they are connected or which fingers may be fitted into suitable receptacles or receivers at the ends of the frame structure permitting such automatic adjustment.

In the drawing, Fig. 1 is a front view of the Window construction with the weather stripping of the present invention attached to the structures.

Fig. .8 is a side sectional view upon the line ti -.8 of Fig. 7.

Fig. 9 is a fragmentaryview of the metal strip which may be stamped .Out of flat metal and bent to form the Weather-stripping of Figs. 3 to 5.

Referring to the drawings, the window of Figs. 1 and 2 is provided with the frame l0 having top and bottom members ii and i2 and side members 13.

Within the frame the side members l3 .of the frame are provided with the inside and outside channels I4 and I5, respectively, in which are respectively received the lower sash l6 and the upper sash l1. Each of the sashes 1:6 and I1 respectively is provided with frame structures [8 and I!) (see Fig. 2) which frame structures are provided with the upper horizontal members 2!] and 2|, the lower horizontal members 22 and 23, and the side members 24 and 25. Each of the sashes is provided with a glass pane, respectively, 26 and 27.

As indicated in Fig. 2, the upper window frame H is provided with the grooves in channels 2.! 2-8, the latter for receiving the sash 56 when in its uppermost'position and the sill or lower frame member [2 is provided with the recess 29 for receiving the sash member I in its normal lQWermost position and is also provided with the level sill surf-ace The intermediate ridge 3| separates the channels l4 and I5 and the slidin :Sashes t5 and H. The sashes l6 and H, as shown in Figs. 1 and 2, abut each other to close the frame opening Ill, and to .open the interior .of the room to the outside, the sash i6 is lo r d and/ th ash l is raised.

:The 'window and. sa h structure so far described do not form part of this invention which is primarily directed to the weather stripping associated with such sash structure.

Referring to Figs. 3 to 8, it will be noted that the particular teature of the present invention resides in having the weather stripping carried upon the sash members and not on theirame members, the Weather stripping being substantially concealed within the channels i4 and I5 in which said sash members 16 and I] slide.

It is a particular feature of the present invention that the sheet metal forming the weather stripping is so formed that it will of itself have the necessary resiliency to assure a substantial weather seal regardless of relative separation or contraction between the sash and the frame, as with varying climatic conditions or upon aging.

t is also a particular feature of the present invention that the upper and lower horizontal edges of both sash members I6 and I! may be weather-prcofed in substantially the same fashion as are the side edges of the sash members it and H.

Referring to the side weather-stripping 35, shown in Figs. 3 to 5 and 9, this weather-stripping 35 may be formed by stamping a sheet or strip of metal, as indicated in Fig. 9, to have the two side portions it and 4|, which side portions may be bent in respect to each other along the dotted line 42 to form an acute angle, as best indicated in Fig. 3. t will be noted that the angle between the side portions 40 and 4| is relatively so acute in respect to the right angular edge 43 of the sash 25 that contact will only be made along the edges at 44 and 45.

The natural resiliency of the sheet metal making up the angle sa-m will be such as to permit separation or movement together of the sides 4(idl, whereby a perfect seal will be assured across the space 45 at the side of the sash as well as the space M at the front or rear of the sash. As the spaces and/or 41 increase, the angle between the sides 404I of the strip will decrease, and as the spaces 46 and/or 41 increase, the sides 46-4! will be moved apart with increase of the angle of the strip.

As indicated in Figs. 5 and 9, the upper edge of the strip is slit at 4'! to form the fingers 48 and 49, and the lower end is similarly slit, as indicated at 50, to form the fingers 5| and 52.

The fingers 4S and 49 are preferably each provided with the elongated eyes 53 and 54 (see Figs. 4 and 5), which when they are bent downwardly, as indicated at the upper part of Fig. 5, register so that a single screw member or nail 55 .(see Fig. l) may be passed through the slots 53 and 54 into the top of the frame of the sash member, as best indicated in Fig. 4.

The lower fingers 5i and 52 may be similarly constructed and attached to the sash frames to 23, as indicated in Fig. 4. The grooves 53 and 54 enable the fingers 48 and 49 to move upon the post or screw 55 to enable automatic adjustment of the strip.

In Fig. 6 is shown one form of a top and bottom sealing strip 59 which may also be conveniently stamped out of a sheet or strip of metal and attached to the lower edges of the frames, as indicated in Figs. 1 and 2.

As indicated, the strip is provided with the vertical side ii! and the horizontal side 62, which are bent in respect to each other at the line 63.

The slots 64 and 65 may receive suitable posts, screws, or nails, as indicated at 66 in Figs. 1 and 2, enabling ready attachment of the upper and lower sealing strips, and also automatic adjustment thereof.

These upper and lower sealing strips 60 are preferably also formed with an angle substantially more acute than the angle of the sash frame to which they are attached, so that they will expand when the sashes are moved out of their grooves or contacts with each other, as indicated in Fig. 2, and so that they will be pressed into position against the sash edges, as indicated at fill in Fig. 2, when the sashes are respectively elevated and lowered to the closure positions.

It will therefore be noted that applicant has provided a simple, weather stripping attachment for sashes which may be directly attached to the sash and which therefore may be most inexpensively applied and is particularly readily concealed within the sash and frame construction for the most part.

The weather stripping, as indicated, may be readily stamped out of sheet metal and the bending of it into desired shape automatically assures a resilient seal, when such stripping is connected to the sash structure.

It will also be noted that the slotted connection of said weather stripping to the sash structure enables substantially automatic adjustment thereof to take care of opening and closing of the sashes and expansion and contraction of the sashes with varying humidity and temperature conditions.

In Figs. '7 and 8 is shown an alternative method of attaching the ends of the weather stripping to the sash frame to allow for automatic adjustment thereof, similarly functioning parts being indicated by the same numerals as in Figs. 1 to 5 but primed.

In Figs. 7 and 8 the top of the sash frame, as indicated at if, is. attached to the folded-over plate 15 having an upper plate portion 16 and a lower plate ll, which form the intermediate slot 18. The plates are provided with the corresponding openings 19 receiving the screw 80 which fits into the top of the sash 2 l The upper plate is provided at one forward corner with the downwardly projecting tit 8|.

In this construction the upper end of the strip 35 is slit merely to form the bent-over angle members 82 and 33, which as indicated in Fig. '7, fit into the slots E8 on either side of the tit 8| and the screw 80. This arrangement permits an automatic adjustment of the weather strip 35 to accommodate relative expansion or contraction of the window frame ID and sash frames I8 and I9.

It is apparent, of course, that many changes and modifications might be made in the structure shown, and that the end construction shown in Figs. 5, 6, '7 and 8 may be modified or arranged in different combinations and it is intended to cover all such modifications or alterations as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A weather stripping for connection to the edges of sashes to be placed in window frame constructions, said weather stripping being formed of sheet metal stampings, in the form of elongated strips, the sides of which are angularly bent in respect to each other, and the ends of which strips are provided with slots, whereby said strips may be automatically adjustably fitted upon the window sash constructions.

2. In combination with a sash, a weather stripping comprising acutely angularly disposed side portions, which side portions are slit from each other so as to form fingers, said fingers being slotted, and when bent being adapted to overlay one another so said slots will register, and means to connect said fingers to said sashes.

3. In combination, a channeled window frame, a sliding sash received in the channel of said window frame, and weather stripping; carried by the sash fitted in the portion of said sash frame received in said channel, said weather stripping consisting of an elongated angular strip of sheet metal, the angle between the sides of which are more acute than the edge of the sash, whereby a resilient seal is had between the edge of the sash and the channel of the window frame, the end of said weather stripping being slotted toenable connection to said sash.

4. In combination, a channeled window frame, a sliding sash received in the said window frame, and weather stripping carried by the sash, said weather stripping consisting of an elongated angular strip of sheet metal, the angle between the sides of which are more acute than the edge of the sash to which it is attached, whereby a resilient seal is had, the attachment of said stripping to said sash being formed by providing a bent-over metal plate at one edge of the sash I and by slotting the end of the strip to form two tongues to be inserted into the slot between the upper and lower sides of said plate.

5. In combination, a channeled window frame,

a sliding sash received in the said window frame,

and weather stripping carried by the sash, said weather stripping consisting of an elongated angular strip of sheet metal, the angle between the sides of which are more acute than the edge of the sash to which it is attached, whereby a resilient seal is had, the attachment of said stripping to said sash being formed by splitting the stripping and slotting and bending over the fingers formed by the splitting so that the slots will register and receive a screw or nail.

6. In combination, a channeled window frame, a sliding sash received in the said window frame, and weather stripping carried by the sash, said weather stripping consisting of an elongated angular strip of sheet metal, the angle between the sides of which are more acute than the edge of the sash to which it is attached, whereby a resilient seal is had, the attachment of said stripping to said sash being formed by providing slots in the ends of the stripping to receive screws or nails for attachment to the sash.

7. In a weather stripping for a window sash construction, an acutely angled metal strip fitted upon the less acutely angled edge of the sash, the ends of said strip having a slotted connection to the sash to enable automatic adjustment thereof.
